Information
The diagnostic trouble code indicates that the immobilizer codes do not match between the engine control module (ECM) and central electronic module (CEM). The code is also generated if CAN-communication between engine control module (ECM) and central electronic module (CEM) is missing.

Among others, the code may be caused by:
- Engine control module (ECM) is not programmed or has incorrect code for immobilizer, that is, the code does not match the code stored in central electronic module (CEM).
- Central electronic module (CEM) is not programmed or has incorrect code for immobilizer, that is, the code does not match the code stored in engine control module (ECM).
- Open circuit in CAN-communication between central electronic module (CEM) and engine control module (ECM)
- Programmed engine control module (ECM) or central electronic module (CEM) has been moved from one vehicle to another.
